such .as sulphurcompounds, and to subse- 1 quently pass the liquids so contaminated over orous coke for the purpose of restoring it to lts original condition for re-use. Such" procedure, however, as heretofore conducted, has

-. been inefiicientin that thorough cleansing of the gas was not obtained, and has been expensive by reason of the large apparatus required.

-- The invention accordingly com rises the several steps and the relation an. order of each :of the others, and the'a paratus emfeatures of construct on,- combinabodying ,tions elements and arrangement of-parts which are adapted to effect such steps,- allas;

* exemplified in the. following detalled disclosure, and, the scope of the a plication of which'will be indicated in the c aims.

For a fuller understanding of the nature. and objectsof the invention reference should Q be had to the following detailed description taken .inconnection, w th the. accompanying:

upper chamberis intended" intended to reactivate the purifying solutions,

The-upper chamber has a gas Inlet 5 near its lower end, and a gas outlet 6 at its upper end,

while-the-lower chamber has an' air inlet! at its lowerend and an" air outlet 8 at its up per end. A shaft 10 is disposedaxia'lly wit in the casing, having a bearing .11 in'a s ider 12 at the top of the casing, a bearing 13 in the partition 2 and a bearing l t/in a spider 15 at the bottom of the casin A motor 16, which may be mounted outsi e the casing, operates the shaft 10 by bevel gears 17 and 18.-"

I may now refer more particularly to the v gas purifying apparatus in'the upper cham-' her. A plurality of disks 20 are mounted upon the-shaft 10 in vertically spaced relation, and'means are providedfor supplying liquid to each of thesedisks so that as the be projected tangentially from the eriphery.

Liquid is supplied to the upper dis through i an nlet pipe '21, and by that disk projected to the walls of the casing. A plurality ofcpn thecasingr just below each disk, as'shown at T disks are rotated by the motor 16, a spray will I one or. more of such. steps with? respect to 22, which are so designed as to form, with the pocket 23 and discharge the liquid on the in.- nen-portion of thenexnil'ower disk; Below lowermost disk, however, the bafile 25 may conveniently be-inclined downwardly toward thecenter, there being no lower disk to receive its discharge. This baflle assists in preventing the li' uid from splashing-outof' nder many circumstances A it may be desirable-to associate withgthe up- 7 the inlet orifice.

Aconvenient liquid for usein this apparatus is an a 'ueous solutionoficausti'c soda 1a which, when rought into intimate contact with the gas, has" a ca acityto abs'orb the noxiousfumes containe within the gas, such,. for.example,'as.sulphur dioxide.-

tion for re-use, it is passed through the lower portion of the apparatus, which is generally similar to the upper. In this lower apparatus, which may be termed the actifier, be-

" cause of its, action upon the solution, there v may absorb from it the noxious fumes, re-

storing the caustic to its original condition.

Liquid thus entering theupper chamber at the top thoroughly cleanses the gas of impurities and thus becomes contaminated; it then enters the lower chamber at the top, here it gives up its impurities tothe air, which is drawn through the apparatus, just as in the coke towers at present in use. Finally, after purification, it passes into a sump at the f bottom of the apparatus, from whence it is circulated to thetop of the apparatus by a pump 36.

An auxiliary source of liquid is shown at 37, which may feed to the a paratus fresh 30 solution at any time found esirable.- The gas and the air are moved through the apparatus in any convenient'manneryas illustrated, it is intended that the gas be drawn through the apparatus by a fan (not shown), while a fan 38, mounted upon the shaft 10 at the upper end of the lower chamber, is arranged In order to conduct the liquid from the upper chamber to the lower, there may be provided at the bottom of the upper chamber a. conical deflector 39, communicating with the pipe 40, which conducts the liquid to the upper disk of the lower chamber. If the air on leaving the outlet 8 is sufliciently objectionable to make it necessary, it may be disposed of inany con: venient manner. By this construction it will be seen that in a single apparatus the as is purified and the purified liquid reacti ed in a thorough'and eflicient manner, and with a minimum of apparatus.

Since certain 'changes in carrying out the above process, and in the constructions set forth, which embody the invention, may-ha madewithoutedelparting from its scope, it is intended that a matter contained in the "above description or shown .in the accompanying drawing shall be interpreted as illustrative and not in a limitin It is also to be understood lowin claims are intended. to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might .be said to fall therebetween.
